Getting started with the Azure IoT Central Rest API

Azure IoT Central is a SaaS platform for IoT projects.

If you are looking for a way to manage and monitor your IoT devices outside the Azure Portal or are not able to build your own IoT platform, IoT Central is the place to be. And you can extend this portal with custom Azure resources using the export functionality.

All you need is to have browser access to Azure IoT Central. You can even run it for free for seven days to test it out. Also, the first two devices registered are free too.

Once you have worked with Azure IoT central, you have mastered it using the portal. If you want to scale up eg. the number of devices or users, automation of your tasks becomes necessary.

For this, Azure IoT Central offers a Rest API.

Let’s check this API out.

Counting the current number of IoT Hub messages and devices

Microsoft provides SDKs for both building IoT devices and accessing the IoT Hub (based on several programming languages).

Regarding the IoT Hub, with the SDK you are able to eg. register and control devices.

Still, some actions are possible with the IoT Hub which is not supported by the SDK.

For those actions, Microsoft supports an IoTHub Rest API which extends the capabilities of the SDK.

In the past, I demonstrated how to work with C2D messages using the REST API.

A few days back, I came along with this MS Learn question about IoT Hub message counts. This also has to be tackled by the REST API.

Let’s see how.
